Session: Enhancing Behavior Therapy for Trichotillomania

2 - (SYM 140) Moderators and Processes of Change in a Randomized Waitlist-controlled Trial of a Fully Automated Website Delivering AEBT for Adults with Trichotillomania

Sunday, November 19, 2023
10:30 AM – 12:00 PM PST
Location: Chiwawa (501), Level 5

To effectively research and disseminate evidence-based treatments, it is important to understand what treatments and modalities of delivery are efficacious, and the processes of change that lead to decreases in symptom severity. This study assessed moderators of treatment outcomes and processes of change from a randomized waitlist-controlled trial (RCT) of a fully automated website delivering acceptance-enhanced behavior therapy (AEBT) for adults (N= 81). The primary outcomes of the RCT included significant decreases in trichotillomania symptom severity (53% of participants met treatment responder status) and psychological inflexibility. Moderators of treatment outcomes included baseline psychological flexibility, baseline anxiety, and age. Processes of change included changes in psychological flexibility and anxiety over time on symptom severity. These findings highlight the role of trichotillomania psychological flexibility on treatment outcomes. The implications of these findings will be discussed.
